This is a very important topic.
If you want to watch UK TV channels through internet of course.
Nigel is right - if there is no Fiber Optic - then you are unlikely to get it in the near future.
There is a page on the Movistar website that you can test your area, but it is still very limited.
Basically, if Movistar want to improve the service they will, if they don't they don't.
Although this said a friend bullied Movistar into upgrading the system on his line (B*** the neighbours!) and they did!!
We are in AEG pueblo and get on averge 8mbps on a good day (at non-peak times ;)
I think we pay for 10. But everyone knows you don't always get what you pay for!
If you get stuck, I have a friend who sells an IPTV system that works on just 1Mbps! (But no HD of course at that speed ;)
